Thanks in no small part to mobile phenomenon Puzzles & Dragons, GungHo has a pretty absurd operating profit margin — 57 percent or so this past quarter. But with revenue and profits down 5 percent and 12 percent, respectively, quarter over quarter, the companies price fell sharply this week.

Since the reveal of the numbers, the stock price in Japan fell from ¥80,000 down to ¥60,000. Meanwhile, GungHo recently purchased a controlling stake in the studio behind the other current huge mobile title Clash of Clans.
